WASHING macnnm Application filed m 15, 1922. Serial no. 575,338.

To all whom it may concern:-

Be it known that I, JAMEs F. Evnnn r'r, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and.

State of Illinois, have invented certain new and useful Improvements in Washing Ma: chines, of which the following is a spamfication.

My invention relates to improvements in washing machines and more particularly to washing chambers therefor, the object of the invention bein to provide a simple and eflicient washing c amber which is capable of economical manufacture and is highly efiicient in use.

Other objects will appear hereafter.

The invention consists in the combina-. tions and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1, is a vertical transverse section of a washing machine equipped with a washing chamber embodying the invention,

Fig. 2, is a section at right angles to 1, ig. 3, is an enlarged detailed section through .a portion of the periphery of the washing chamber.

The preferred form of construction, as illustrated in the drawings, comprises an outer substantially hemispherical bowl 4 preferably made of concrete material and mounted on a suitable pedestal or base 5, as indicated. A removable cover 7, also substantially hemispherical in form, is secured to the bowl 4, as shown, and-provided with a suitable door 8. The bowl 4 is provided with a suitable distributing passage or channel 9 into which leads a supp 1pc 10 by means of which the washing is supplied to the interior of the washing machine. A suitable discharge valve 11 is provided in the bottom of the bowl 4. for discharging the washing fluid.

Arranged within the casin thus formed is a revolving washing cham er, or drum, 12 substantially globular in form and consists of two hemispherical halves, each provided with a trunnion 13 suitably mounted to rotate in the outer casing of the machine,

as indicated. Each of the hemispherical halves is provided around its edges with an inwardly extending flange 14 having re-.

which tend to lift the clothes within the washing chamber as the same revolves. Hubs '19 are also formed in the interiors of the washing chamber parts at the junc tures of the ribs 16 and whereby the formation of acute angle recesses at these points is prevented. The washing chamber parts are each formed from a single casting and subsequently secured together to complete the washin chamber the walls of which are perforated to admit the washing water thereto.

One of the trunnions 13 carries the driving gear 20 meshing with a pinion 21 on an electric motor 22 and by means of which the washing chamber will be constantly driven in one direction. A suitable door 12 is provided for the washing chamber and by means of which the clothes to be washed may be readil inserted .or removed.

In use the c othes are placed in the washing chamber and a suitable amount of washing fluid sup lied to the machine. The washing cham er is then constantly rotated in one direction, the clothes being picked up by the ribs 16 and carried upwardly thereby until the reach a position adjacent the top when'tliey fall throu h gravity. The recesses 15 in the sides of t e spreader rib. 14-14 tend to formvacuumsto cause the clothes to cling to said rib, thus assisting in this lifting action. Likewise, the

recesses 18 tend to form effective engageefliciently washed without entanglement.

The form and arrangement of the washing chamber disclosed is a simple and efiicient I one which may be manufactured economi cally.

While I have illustrated and described the preierred form of construction for carrying my invention into eii'ect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A washing machine comprising a washing chamber substantially spherical in form and mounted to rotate upon a horizontal axis; and a spreader rib substantially at the center of the inner walls of said chamber and extending around the axis of rotation in a plane substantially perpendicular thereto, the sides of said rib being provided with, recesses, substantially as described.

2. A washing machine comprising a washing chamber substantially spherical in form and mounted to rotate upon a horizontal axis; and a spreader rib substantially at the center of the inner'walls of'said chamber and extending around the axis of rotation in a plane substantiall perpendicular thereto, said spreader ri being of different heights at different (portions thereof, substantially as describe 3. A washingmachine comprising a washing chamber substantially spherical in form and mounted to rotate upon a horizontal axis; a spreader rib substantially at the' center of the inner walls of said chamber and extending around the axis of rotation in a plane substantially perpendicular thereto, said spreader rib being of different heights at diflerent portions thereof; and the sides I of said spreader rib being provided with recesses, substantially as described.

4. A washing chamber for washing machines substantially spherical in form and.

mounted to rotate upon a horizontal axis; ribs on the mner walls of said washing chamber extending along the inner periphweaves ery thereof from points adjacent the axis of rotation on one side to corresponding points adjacent the axis of rotation on the of rotation on one side to corresponding points adjacent the axis of rotation on the other side; a spreader rib substantially at the center of said chamber and extending around the axis of rotation in a plane substantially perpendicular thereto, said spreader rib being higher midway between said first mentioned ribs and decreasing in height toward said first mentioned ribs, and the sides of said spreader rib being provided with recesses. l

6,. A washing chamber for washing machines comprising two substantially hemispherical parts; and inwardly extending flanges at the edges of said parts adapted and arranged to be secured together to form a substantially globular chamber, substantially as described.

7. A washing chamber for washing ma chines comprising two substantially hemispherical parts; inwardly extending flanges at the edges of said parts adapted and arranged to be secured together to form a substantially globular chamber; and ribs on the inner walls of said parts substantially perpendicu'lar to the flanges thereof, substantially' as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
